Let us recap what we have learned in this chapter. We saw several ADF business components; they are entity object, association, view object, view link, and application module. The interactions between these objects are also discussed. The runtime behavior of the components is explained and the CRUD operations are performed using these business components. Various options available for the components are also examined.
In the next chapter, we will see how to do the validation for the ADF model layer. We will learn more about the declarative validations and the APIs available for the business components.
